I found this issues when I attempt to use contains for System.Array.
Having the errors
Page: Initialise
Stage: Stage1
Type: Error
Action: Validate
Description: Compiler error at line 305: 'System.Array' does not contain a definition for 'Contains' and no extension method 'Contains' accepting a first argument of type 'System.Array' could be found (are you missing a using directive or an assembly reference?)
Repairable: No
Hi, Yes BP5 will support LINQ,
If you want to use Contains functions you need to delcare the data as Generic List not in array format.
Let me know if you need any assistance.
